Power generation, transmission, distribution and protection system equipment of Dutch Bangla Power & Associates Ltd. (DBPAL)

Abstract:

We did our internship at Dutch Bangla Power & Associates Ltd (DBPAL) located at Ailpara, Siddhirganj, Naraynganj on the left bank of the river Shitalakkha from 26th December to 12th of January and this internship report is the result of those 15 days attachment with the DBPAL. During our internship period we gathered practical experiences over the topics related power generation, switchgear protection and power distribution which we have learned inside the class room or from books. In this report we have focused on the processes which are used in DBPAL. For power generation, HFO (Heavy fuel oil which is basically furnace oil) is used in DBPAL. Protection and controlling of the equipments of the power station is a very important and complicated task. With the help of the plant engineers we observed the control room and protective
equipments such as: relays (VAMP 210 & VAMP 265 used in DBPAL), circuit breakers etc very closely and understood the functions and controlling system of those equipments. We acquired knowledge about various types of transformers, isolator, circuit breakers (SF6 and Oil), lightning arresters, current transformers, potential transformers and other equipments of the power station which were clearly taught and shown by the senior engineers of the power station of DBPAL. There are various types of tests (meggar test, motor test, transformer test) which are performed by the technicians and engineers of the DBPAL.
